Components
The components of the back panel are:
• Serial/Network I/O Ports. Ports 1, 2, 3, and 6 are DB-25 connectors. Port 4
is a DB 15 connector.
• AC Power Supply. The rear of the Power Supply has two (male and female)
power source connectors (one is for connection to an AC source and the other
is an AC outlet) along with a selectable 115 VAC or 230 VAC switch. For
most international usage, the switch must be set for 230 VAC.
• DC Power Supply. The unit can be shipped with the -48VDC Power Option.
The terminal block of the -48VDC has 5 screws. The two outermost screws
are for attachment. The negative wire terminal is second from the left; the
positive wire terminal is in the middle; the ground is second from the right.
• Expansion Card Ports. The expansion card ports differ depending on what
card is installed in that slot.
